"[T]he path to zero emissions in manufacturing looks like this: (1) Electrify every process possible. This is going to take a lot of innovation. (2) Get that electricity from a power grid that’s been decarbonized. This also will take a lot of innovation. (3) Use carbon capture to absorb the remaining emissions. And so will this. (4) Use materials more efficiently. Same."
How to Avoid a Climate Disaster: The Solutions We Have and the Breakthroughs We Need is a 2021 book by Bill Gates. In it, Gates presents what he learned in over a decade of studying climate change and investing in innovations to address global warming and recommends technological strategies to tackle it.
"[Question] 1. How Much of the 51 Billion Tons Are We Talking About? . . . Tip: Whenever you see some number of tons of greenhouse gases, convert it to a percentage of 51 billion, which is the world’s current yearly total emissions (in carbon dioxide equivalents)."
"[C]ement . . . steel [and] plastics are cheap because fossil fuels are cheap."
"Offshore wind holds a lot of promise . . . ."
"The reason we need to get to zero is simple. Greenhouse gases trap heat, causing the average surface temperature of the earth to go up. . . . Once greenhouse gases are in the atmosphere, they stay there for a very long time . . . . There’s no scenario in which we keep adding carbon to the atmosphere and the world stops getting hotter, and the hotter it gets, the harder it will be for humans to survive, much less thrive."
"[W]e’re going to need much more clean electricity in the coming years. . . . [B]y 2050 . . . the world will need much more than three times the electricity we generate now."
"I [have become] convinced of three things: 1. To avoid a climate disaster, we have to get to zero {net emissions by the year 2050}. 2. We need to deploy the tools we already have, like solar and wind, faster and smarter. 3. And we need to create and roll out breakthrough technologies that can take us the rest of the way."
